Arduino Due R3 Board DUE-CH340 for ATSAM3X8E

1) Due board runs at 3.3 V. The maximum voltage that the I/O pins can tolerate is 3.3 V. Providing higher voltages, like 5V to an I/O pin could damage the board.
2) ARM core strengths: The use of 32-bit ARM core is more powerful than th previous use of the other Iduino core 8 AVR.

The main differences are:
• 32 bits at a clock can process 32 bits of data.
• CPU clock frequency of 84 MHz
• 96 SRAM KBytes
• 512 Flash KBytes
• A DMA controller, can reduce the pressure on the CPU to do a lot of computing

• Microcontroller: AT91SAM3X8E
• Operating voltage: 3.3 V
• Input voltage (recommended): 7 - 12 V
• Input voltage (limits): 6 - 16 V
• Digital I/O pins: 54 (of which 12 provide PWM output)
• Analog input pins: 12
• Analog outputs pins: 2 (DAC)
• Total DC output current on all I/O lines: 130 mA
• DC current for 3.3 V pin: 800 mA
• DC current for 5 V pin: 800 mA
• Flash memory: 512 KB all available for the user applications
• SRAM: 96 KB (two banks: 64 KB and 32 KB)
• Clock speed: 84 MHz
